Our I/O circuitry on Neuron (unlike the UniPi 1.1) is not directly connected to the Raspberry PI GPIOs, which is what PiGPIO is exclusively based upon - while you can install it, it will not be possible to read the Neuron digital inputs using the PiGPIO library. All references to PiGPIO in EVOK are related to UniPi 1.1.

That said - you can still access the inputs as any other GPIOs, just not with the PiGPIO library, which - as the name indicates - only works with the native RaspberryPI circuitry. Depending on the speed you need you may be able to read the wiegand protocol with the DIs directly, though unfortunately not with the script you linked.
